Container different on 1440 and up

Hi,

I’m trying to put my 2 column layout inside a container.
I have coloured column A in Cyan (This will be populated with an image) and Grey in column B (Where the text will be).

Each column will take up 50% width and 100% height of its parent element.

The issue: This all seem to work fine until I reached the following breakpoints:
1440 and up
1920 and up

Notice how on the 1440 and up the container becomes invisible and
on 1920 and up I had to put Display Block on the container (class name: Card-Dk-2) for it to work.

I would really appreciate your thoughts on this - thanks
